A rep for Peter confirmed to Reveal this week that 23-year-old trainee doctor Emily is expecting the couple's first child and they are "over the moon" about the news.
Peter hasn't specifically mentioned the pregnancy on his Twitter feed, but he did allude to the messages of congratulations from his fans last night.
He wrote: "Thanks to all of you for your awesome messages. You are great :))))"
Speculation that Emily was pregnant arose earlier this year when Peter was seen holding a protective hand over her stomach while at a red carpet event in London.
Last week, 'Mysterious Girl' singer Peter admitted in an online video that he wanted to have another baby, adding that he ideally wanted to be married or engaged first.
Thanks to all of you for your awesome messages. You are great :))))— Peter Andre (@MrPeterAndre) July 23, 2013
Peter is already dad to son Junior, 8, and daughter Princess, 6, with his ex-wife Katie Price, who is also expecting another child.
Katie sent her congratulations to the couple earlier this week, saying: "Genuine congratulations to Pete and Emily and I hope they are very happy."
